Abstract
El estudio se centra en la comparación de la riqueza de órdenes de insectos caminadores en tres ecosistemas y distintas temporadas en el Campus Naturaleza de la Universidad de Concepción, ubicado en la Región del Biobío. El objetivo es evaluar cómo las condiciones ambientales y variación estacional influyen en el ensamble de insectos, expresado en términos de abundancia y riqueza de órdenes. Se realizaron muestreos durante el otoño, primavera y verano, dividiendo el área de estudio en tres ecosistemas: humedal, bosque nativo y plantación de Eucalyptus globulus. Se utilizaron trampas de suelo o pitfall distribuidas aleatoriamente para capturar insectos en cada ecosistema. Los resultados muestran que el o
rden Diptera, considerando el total de las muestras es el más abundante dentro de este estudio
. En primavera, se observó un aumento en los ejemplares de Diptera en los tres ecosistemas y un incremento de Coleoptera en E. globulus. En E. globulus se destacó en términos de abundancia de insectos, mientras que el Bosque Nativo presentó una mayor riqueza de órdenes, lo que refleja una mayor diversidad en este ecosistema. Por ende, para mantener la diversidad de órdenes de insectos en el Campus Naturaleza, se debe buscar la preservación y restauración de los ecosistemas. La creación de corredores biológicos que son fundamentales y el monitoreo de los órdenes menos comunes.
The study focuses on comparing the richness of insect orders across three ecosystems over different seasons at the Campus Naturaleza of the Universidad de Concepción, located in the Biobío Region. The objective is to assess how environmental conditions and seasonal variation influence the insect assemblage, expressed in terms of abundance and order richness. Sampling was conducted during autumn, spring, and summer, dividing the study area into three ecosystems: wetland, native forest, and an Eucalyptus globulus plantation. Ground or pitfall traps were randomly distributed to capture insects in each ecosystem. The results show that, overall, Diptera is the most abundant order observed in this study. In spring, there was an increase in Diptera specimens across all three ecosystems, along with a rise in Coleoptera within the E. globulus plantation. The E. globulus ecosystem stood out in terms of insect abundance, while the native forest exhibited greater order richness, indicating higher diversity in this ecosystem. Therefore, to maintain insect order diversity at Campus Naturaleza, ecosystem preservation and restoration are essential. Likewise, the establishment of biological corridors and monitoring of less common orders are fundamental.
